METHOD OF FORMING TOOLS.

Specification of Letters Patent.

Application filed December 2, 1912. Serial N 0. 734,428.

To all whom it may concern:

Be it known that I, GEORGE E. 001), of Southington, in the county ofHartford and State of Connecticut, have invented a new and ImprovedMethod for Forming Tools, of which the following is a specification.

My invention relates to the making of certain hand tools, as screwdrivers and like articles, and an object of the invention,

' among others, is to form a tool in a manner to avoid injury to thehandle in the operation of securing it in place.

The object hereinabove set out, as well as others, may be attained inthe construction of a tool in accordance wit-h my invention and asillustrated in the accompanying drawings, in which Figure 1 is a view incentral longitudinal section through a tool handle showing part of thesteps in securing a tool thereto in accordance wit-h my invention. Fig.2 is a like view illustrating the final steps in securing the handle inplace.

In the construction of tools of this class it has become desirable to soform the parts that the outer surface of the tool shank, ferrule and thelower end of the handle shall constitute a smooth, continuous v unbrokensurface. Different ways of accomplishing this result have been employed,both by myself and others, but I have found a very satisfactoryconstruction and one having many desirable advantages to reside in atool in which the metal of the shank is swaged up in a manner to forcethe handle rial composing the handle, commonly composed of wood or likematerial, at the point where the shouldered part of the handle comes incontact with the edge of the ferrule.

A tool constructed in accordance with my invention avoids thisobjectionable feature, such tool being shown herein, in which thenumeral 3 denotes its shank formed from metal, preferably round incross-section and usually of uniform diameter throughout, in thepreliminary steps of the operation. A head 4 is formed upon one end ofthis rod of stock, which in the preliminary step, is cut to the properlength. A handle 5 of suitable form and having a central longitudinalopening for the reception of the tool shank is then placed upon thisheaded rod of stock with its end located against the under side of thehead 4:. This handle has a reduced tapered end 6 providing a shoulder 7.A ferrule 8 is then placed upon this rod of stock, by passing it on tothe unheaded end. This ferrule has a recess, the walls 9 of which are ofa thickness substantially equal to the depth of the shoulder 7 Thelength of these walls, or in other words, the depth of the recess 10, issuch that the bottom 11 of the recess shall rest firmly and snuglyagainst the extreme end of the tapered portion 6 of the handle, thuspreventing pressure or force occurring between the edge of the recessedpart of the ferrule and the shoulder 7. After the ferrule has beenplaced in position the shank of the tool is swaged up tightly againstthe end of the ferrule to force it snugly against the handle, thisswaged portion 12 being formed in any desired manner providing ashoulder 13, between which and the under side of the head 4 the handleand ferrule are tightly secured. The handle of a tool thus formed haslittle chance of loosening, and liability to injury, and consequentdamage and loss in constructing the tool is reduced to a minimum.

It will be understood that in the finished tool the edge of the ferruleWithin which the recess is formed rests closely enough in contact withthe shoulder 7 to provide a smooth continuous unbroken surface, that is,without space between the parts, but without pressure at this point. Inorder to emphasize this feature and clearly bring out the fact thatthere is no pressure at this point, a slight space is shown in thedrawing but it will be understood that this space does not occur in atool constructed in accordance with the invention.

After the tool has been secured in place the end opposite the handle maybe formed into any suitable shape to provide the tool desired, a screwdriver blade 14 being shown herein.

While I have shown and described herein one way of constructing myimproved tool it is not absolutely essential that this shall be closelyfollowed, as it may be departed from to a greater or lesser extentwithout avoiding the invention.

I claim 1. The method of making a too-l that consists in forming a headat the end of a rod of stock, placing a shouldered handle there- 011against said head plaeing a ferrule on said rod with the end of thehandle firmly seated in the ferrule and then swaging the metal of therod tightly against the end of said "ferrule.

2. The method of making a tool that consists in forming; a head at theend of'a rod of stock, placing a shouldered handle there on against saidhead,-1 3lae ing tLIfOIlUlQ on said rod with the end of the'handlefirmly seated in, the ferrule andthen finally forming a shoulder on therod by swaging the metal of the rod against the end of the ferrule.

3. The method of making a tool that cons1sts 1n forming a head upon arod of stock, plaelng ahandle having a reduced shouldered end-upon therod against said head,

placing a ferrule with a recess slightly less in depth than the lengthof said reduced shouldered part upon the rod with the end 1 of thehandle seated firmly against the bottom of said recess, and then swagingthe metal of the shank-tlghtly against the end Copies of this patentmaybeobt'ained for five cents eaeh,' by addressing the Commissioner ofPatents.
